Answer 1

•°• Diatas meja terdapat kaleng susu berbentuk tabung yg memiliki 20 cm dan jari² 14 cm, kaleng susu tersebut berisi susu yg masih penuh,jadi volume kaleng susu tersebut adalah [tex]\underline{\boxed{\red{\bf{12.320~cm³}}}}[/tex]

Penjelasan dengan langkah-langkah:

• Jari-jari = 14 cm
• Tinggi = 20 cm
• Volume = ? cm³

[tex]\sf{V_{Kaleng}}[/tex] = [tex]\sf{V_{tabung}}[/tex]

[tex]\sf{V_{Kaleng}}[/tex] = [tex]\sf{L_{alas} × tinggi}[/tex]

[tex]\sf{V_{Kaleng}}[/tex] = [tex]\sf{π × r × r × t}[/tex]

[tex]\sf{V_{Kaleng}}[/tex] = [tex]\sf{\dfrac{22}{\cancel{7}} × \cancel{14} × 14 × 20}[/tex]

[tex]\sf{V_{Kaleng}}[/tex] = [tex]\sf{22 × 2 × 14 × 20}[/tex]

[tex]\sf{V_{Kaleng}}[/tex] = [tex]\sf{44 × 14 × 20}[/tex]

[tex]\sf{V_{Kaleng}}[/tex] = [tex]\sf{616 × 20}[/tex]

[tex]\sf{V_{Kaleng}}[/tex] = [tex]\underline{\boxed{\red{\bf{12.320~cm³}}}}[/tex]
